Can a stressed fish recover?

Aquarium fish can become stressed by any number of things ranging from poor water quality to disease to changes in tank parameters. In some cases, mild stress is something your aquarium fish can recover from but, in many cases, it is an early sign of something that can become a major problem.

Why are my fish staying in one corner?

Just like sickness, they stay in the corner because they feel vulnerable. Unfortunately, there's not much you can do for this one except wait for it to pass.

Is it normal for fish to stay still?

When the water temperature inside your aquarium drops too low, your fish might lay motionless at the bottom of the tank to conserve energy. On the opposite spectrum, if the water temperature rises dangerously high, fish will stay on the bottom because that's where oxygen levels will be higher.

What to do if your fish is sitting at the bottom of the tank?

Are water changes stressful for fish?

When a sudden, large water change occurs, it causes such a drastic shift in the water parameters that the fish often cannot tolerate it and they die. 2 Those that do not die immediately are stressed and may succumb to disease over the next few weeks.

How do I know if my fish tank has too much oxygen?

The signs of too much oxygen in a fish tank are bubbles escaping the surface and increased dissolved oxygen levels. Fish will also show abnormal swimming behavior, open mouth breathing, excessive appetite, or lethargy. If left unchecked for too long, it can be fatal to the fishes' health.
